KEK Director General assesses earthquake damage, tells repair plans

Atsuto Suzuki, Director General at KEK, the Japanese high energy accelerator research organization, reported on damage caused by the recent earthquake and recovery prospects in his “DG’s Corner” column: First of all, I would like to express my deepest appreciation for the messages of concern, sympathy and encouragement that we...

Superconductivity pioneer Paul Chu featured in exhibit

Superconductivity Pioneer Paul Chu was featured in an unusual exhibit in Texas. A white lab coat and a pair of worn sneakers are almost standard-issue items for a research facility, but they don't seem to rise to the rank of museum exhibit. Yet, that’s exactly where you can find one...

Paul Chu expected more progress by now

Superconductivity pioneer Dr. Paul Chu expected faster progress since his discoveries, he told Cold Facts Editor Theresa Boehl in a recent brief interview. Cold Facts: Did you have any idea of the potential impact of superconductivity when you were doing your groundbreaking research years ago? Chu: Yes, I think I...

NASA to send up teachers on SOFIA

NASA has selected six teachers to work with scientists aboard the Stratospheric Observatory for Infrared Astronomy (SOFIA) during research flights in May and June. This is the first team of educators selected to participate in SOFIA’s Airborne Astronomy Ambassadors program.

LBNE Takes a “Hive’s Worth” of Experts

In the May symmetry, in an article titled, “LBNE: the inside buzz on a new science project,” Amelia Williamson Smith reports that planning and designing the $900 million Long Baseline Neutrino Experiment takes more than a village. It takes a hive’s worth of scientists, engineers, technicians, accountants, and other specialists...

Helium II

Helium II (He II) refers to the second liquid phase of the most abundant helium isotope (4He). Helium II is also referred to as superfluid helium. Helium II occurs once the temperature of the liquid helium drops below 2.17K. The phase transition between the first liquid phase of Helium (referred...

Bose-Einstein Condensate

A Bose-Einstein condensate, first proposed in 1925 by Albert Einstein based on work done by Satyendra Nath Bose (the same Bose from whom the term boson is derived), is a super-cold state of matter in which almost all of the individual atoms have “condensed” down to the lowest possible quantum...

Cold Technology for Pest Control

While it does not reach temperatures cold enough to be called cryogenic, carbon dioxide snow is at the heart of a new way of dealing with unwanted pests. It utilizes a quick freezing process that takes advantage of the properties of carbon dioxide snow and has a number of benefits...

Thermal shock on steel cylinder when dropped into liquid nitrogen

We are a research team at the University of South Florida, studying the “thermal shock” on a steel cylinder when it is dropped into liquid nitrogen. We want to make sure that the thermocouple does not get influenced by the surrounding LN2. Any advice?

Getter materials to absorb out gassed materials?

Here’s one for the scientists: We would like to sell vacuum insulated pipe for high temperature fluid applications. Are there any good getter materials that we can place in the vacuum space of our VJP to absorb outgassed materials at elevated temperatures?

Data on Carbon Fibres Reinforced Plastic at temperatures between 4 and 300K.

I am looking for data on Carbon Fibres Reinforced Plastic at temperatures between 4 and 300K. I would appreciate it if someone could give me some hints on where to find it.
